javascript - Appium iOS获取上下文不起作用

我正在开发一个 iOS React-Native 应用程序。现在我正在为登录功能进行集成测试。为了登录我们的应用程序，用户需要打开电子邮件并点击一个链接。

我想用 Appium 集成测试做什么: - 打开 native 应用程序。 - 按应用程序中的按钮发送电子邮件 - 打开浏览器和gmail - 查找电子邮件并单击链接登录 - 返回应用程序进行其余测试

但是，我在打开电子邮件时遇到了问题，我认为这是因为驱动程序的上下文有误。但是，当我尝试使用 driver.contexts() 函数获取可用上下文时，我只会收到一个错误并且根本没有上下文。

为什么 driver.contexts() 函数不起作用？我尝试做的事情合理吗？

我的测试 stub 如下所示:

import wd from 'wd'
import { config, port } from '../appiumConfig'

const driver = wd.promiseChainRemote('localhost', port)

describe('Login', () => {
  beforeAll(async () => await driver.init(config))
  afterAll(async () => await driver.quit())

  it('Should get contexts', async () => {
    await driver.contexts((err, handle) => {
      if (err) { // Error!
        console.log(err)
      }
      console.log(handle)
    })
  })
})

Appium 配置如下:

"ios-emulator": {
    "platformName": "iOS",
     "platformVersion": "11.3",
     "deviceName": "iPhone Simulator",
     "app": "./ios/build/Build/Products/Release-iphonesimulator/myApp.app"
   }

我得到的错误是:

{"message":"[contexts()] Error response status: 13, , UnknownError - An unknown server-side error occurred while processing the command. Selenium error: An unknown server-side error occurred while processing the command. Original error: connect ECONNREFUSED ::1:27753","status":13,"cause":{"status":13,"value":{"message":"An unknown server-side error occurred while processing the command.

编辑:这也是我在 Appium 服务器上遇到的错误:

Best Answer-推荐答案

它对我来说非常适合原生应用程序

wd.js v1.6.1

appium 服务器 v1.7.2

节点 v7.9.0

npm v4.2.0

Mac OS Sierra 10.12.6

代码与你的相似:

const wd = require('wd')

const driver = wd.promiseChainRemote(server)
await driver.init(desired)
const contexts = await driver.contexts()

服务器日志:

> CALL init({"platformName":"iOS","platformVersion":"11.1","deviceName":"iPhone SE","automationName":"XCUITest","noReset":true,"app":"/Users/dmitry/Downloads/Nigeria-TEST.app"})

> RESPONSE contexts() ["NATIVE_APP"]

您的日志状态错误 ECONNREFUSED 意味着您的 appium 服务已关闭，可能它在处理请求时崩溃了 -> 检查完整日志以了解发生了什么。

我想说这个问题很可能是因为您试图在同一个 session 中执行所有步骤(重用相同的驱动程序实例)。 尝试在单独的 session 中进行浏览器导航到 gmail，然后返回使用第一个继续进行应用程序测试。多个应用 session 开始使用 XCode 9，因此它可能会有所帮助。
